What is the art of arranging letters and text to enhance legibility and visual appeal?

The practice of arranging letters and text to improve both legibility and visual appeal is known as typography. Typography encompasses various elements, including font selection, size, line spacing, and letter spacing, which collectively contribute to the readability and aesthetic quality of text. A strong understanding of typography is essential in interactive design, as it ensures that written content is not only functional but also engaging and easy to read on various devices.

While color plays a significant role in design, it primarily affects the emotional tone and visibility rather than the arrangement of text itself. Designing interface focuses more on the overall interaction and functionality of a user interface rather than the specific art of letter arrangement. Layout involves the overall arrangement of visual elements on a page, which can include typography but is a broader concept that encompasses more than just text arrangement. Thus, typography is the most precise term for the art of manipulating text to enhance clarity and visual attractiveness.
